Continuous improvement to optimize bearing performance in the field

With improvements such as surface finishes and heat treatment, upgraded SKF Explorer spherical roller bearings can have a service life twice that of the previous industry-leading SKF Explorer bearings, especially under contaminated or poor lubrication conditions (Diagram 1 and Diagram 2).

Sealed SKF Explorer spherical roller bearings can significantly increase bearing service life in contaminated environments. These bearings are pre-lubricated with a specially formulated grease and sealed with highly effective contact seals. By eliminating or extending relubrication intervals, these bearings can significantly reduce the cost to purchase, apply and dispose of grease. Reduced maintenance costs will, in many cases, substantially reduce the total cost of ownership of an application.

With a new design that results in up to 50% less seal friction, small sealed SKF Explorer spherical roller bearings reduce operating temperatures by as much as 20 °C (36 °F) (Diagram 3), enabling us to double the limiting speed rating. As a result, more applications can benefit from the superior contamination protection of sealed SKF Explorer spherical roller bearings, including:
